摘　　要：The 3-D velocity tomography image of the central-eastern part of Qilianshan is obtained by the joint inversion of 3-D velocity structure and focal parameters based on the S-P data of micro-earthquakes recorded by the digital seismic network set up for a Sino-French cooperation program since 1996. The inversed velocity structure does primarily reflect some important features of the deep structure in the region and provide the scientific background for the further study of active tectonic structure and the calculation of earthquake parameters.The 3 D velocity tomography image of the central eastern part of Qilian shan is obtained by the joint inversion of 3 D velocity structure and focal parameters based on the S P data of micro earthquakes recorded by the digital seismic network of a Sino French cooperation program since 1996.
